ChatGPT-Proxy

Python version of OpenAI's ChatGPT web API proxy
Python alternative of ChatGPT-Proxy-V4
Use cookie cf_clearance to pass Cloudflare browser check

_puid no longer works

Requirements

• Access to chat.openai.com

Install

pip install chatgpt-proxy

Usage

For how to get a usable cf_clearance cookie, checkout issue #1 (Chinese only sorry)

Run as a service

Set these environment variables:

• CF_CLEARANCE: (Optional) Cookie cf_clearance
• USER_AGENT: (Optional) User-agent of your browser when you get the cookie cf_clearance
• ACCESS_TOKEN: (Optional) Obtains from here
• PUID: (Optional) Cookie _puid, still needed to start a conversation for plus account (?) When set a plus account's access_token, this can be automatically refresh
• PROXY_TRUST_CLIENT: (Optional) Trust requests from any client.
  When set to True, any requests without an access_token will be given the above access_token.
  Default to False, which will only use for refresh puid.
• HOST: (Optional) Listen on host, default to 127.0.0.1
• PORT: (Optional) Listen on port, default to 7800
• MOD_ACCESS_TOKEN: (Optional) Update info like cf_clearance through http request requires you set this access_token in Authorization Header

Or create a .env file with your environment variables at where you want to run the proxy:

cf_clearance=YOUR_CF_CLEARANCE
user_agent=YOUR_USER_AGENT
access_token=YOUR_ACCESS_TOKEN
puid=ANY_VALID_PUID
proxy_trust_client=False
host=127.0.0.1
port=7800
mod_access_token=YOUR_MOD_ACCESS_TOKEN

Note that environment variables will override the values in .env file.

Then run: python -m chatgpt_proxy

Success

If you see this in console: 2023-01-01 00:00:00,000 - chatgpt_proxy.proxy - INFO - puid: user-xxxxxx You are ready to go

The proxy is avaliable at http://host:port/backend-api/

Integrate into your FastAPI app

Check out __main__.py

from chatgpt_proxy import WebChatGPTProxy
proxy = WebChatGPTProxy(cf_clearance=CF_CLEARANCE, user_agent=USER_AGENT, access_token=ACCESS_TOKEN, trust=False)
app = FastAPI()
proxy.attach(app, path="/backend-api")

class WebChatGPTProxy:

• cf_clearance: Cookie cf_clearance
• user_agent: User-agent of your browser when you get the cookie cf_clearance
• access_token: (Optional)
• puid: (Optional)
• trust: (Optional) Trust requests from any client. When set to True, any requests without an access_token will be given the above access_token. Default to False, which will only use for refresh puid.

Behind a http proxy

You need to use the same ip address you used to get the cookie cf_clearance

Set HTTP_PROXY and HTTPS_PROXY or ALL_PROXY environment variables.
This cannot be set in .env file becauce httpx (the package we used to send request) reads from environment variables only. See also httpx#Proxies.
